Did you create a filetype for the xml so you could translate it and how do you know you would be extracting the same text for translation as the text inside the supplied sdlxliff?
I haven't created any special filetype; I have checked the existing filetypes for XML, and there are five of them. I have no idea how the FirstSpirit type is different from them and how to create a new filetype in this case.
What I don't understand is how you get this error when you start off with the xml file and create your own sdlxliff. Did you use a Project perhaps and add the xml file to the same Project as the one containing the sdlxliff? Even like this it should not be looking for an existing filetype.
I have tried all possible ways: adding files to the existing project, creating a new project, and opening files for translation without creating a project.
Does your client have this filetype so they can send it to you?
I have asked them and am waiting for the response.
